Briquette based on four raw materials

21 December, 2022

For more than a year we have worked closely with the ferroalloy producer Eramet, to create a high-strength briquette based on four different raw materials and residues.

More efficient production

Eramet wanted to increase the yield of the ore used when producing ferroalloys. By doing this, they can reduce the needs for virgin materials raw and at the same time reduce the need for other disposals and potential need for landfilling.

Full-scale and full-functioning briquettes

The project has been divided into four different phases. In the last test, 600 tons of briquettes were produced and fed all the way from the raw material yard and into the melt, via conveyor belt. They even survived a couple of falls of about ten meters high, without generating a substancial amount of fines. This means our briquettes worked at least as well as a corresponding feed of a lumpy raw material.

As scrap is becoming the new ore, the world needs a solution that ensures all residues are taken care of in the best possible way.

Some residues are more difficult to find benefits for, than others. But in order to reduce the need for virgin raw materials, Eramet teamed up with us to find a greener solution for their ferroalloy production.
